P1596[3]

Int. time field weak. controller

CStat: CUT
P-Group: CONTROL
Sets integral time for field weakening controller.

P1596[0] : 1st. Drive data set (DDS)
P1596[1] : 2nd. Drive data set (DDS)
P1596[2] : 3rd. Drive data set (DDS)
r1597 CO: Outp. field weak. controller
P-Group: CONTROL
Displays output signal of field weakening controller in [%] relative to rated motor flux.
r1598

CO: Flux setpoint (total)

P-Group: CONTROL
Displays total flux setpoint in [%] relative to the rated motor flux.
P1610[3] Continuous torque boost (SLVC)
CStat: CUT
P-Group: CONTROL
Sets the constant torque boost for the low frequency range when sensorless closed-loop vector control is
being used (SLVC). The parameter is entered as a % referred to the rated motor torque (r0333).
For sensorless closed-loop vector control, when the motor model is disabled, an absolute current is
impressed. P1610 represents the maximum load that occurs at a constant setpoint.

P1610[1] : 2nd. Drive data set (DDS)
P1610[2] : 3rd. Drive data set (DDS)
Caution:
P1610 should always be set at least 10% higher than the maximum steady-state load that occurs.
Note:
- For P1610 = 0 %, a current setpoint is calculated that corresponds to the no-load case (rated
magnetization current).
- For P1610 = 100 %, a current setpoint is calculated that corresponds to the rated motor torque.
